Summary: It is a remake of the 2016 Hindi-language film Nil Battey Sannata (The New Classmate).
Sujatha Krishnan (Manju Warrier) is a high-school drop-out, a young widow and a single mother in living in the city of Thiruvananthapuram. She lives to see her daughter Athira 's (Anaswara Rajan) academic success, taking up more and more trivial jobs at apartments and factories to support her schooling (and the planned expensive "private coaching" for SSLC). Her daughter, though, is far from grateful. She is unmotivated, never studies properly, gets low marks in her school exams and won't quit believing that she can't be anything more than a petty "domestic help" like her mother. Sujatha narrates her dilemma to her rich employer George Paul (Nedumudi Venu). A kind and open-hearted man, he tells Sujatha about an uncanny solution to her daughter's poor academic performance. Under the new plan, Sujatha will enrol in her daughter's school so that she can learn math and tutor Athira herself. This embarrasses young Athira. Sujatha slowly starts impressing her classmates and scores pretty much well in maths exams. No one, except for the school's kind principal, is aware of Sujatha's relationship to Athira. Athira begs her mother to stop attending the school. She is angered by her mother's success in math, as she herself continues to fail to understand it. Both of them starts a rivalry where if Athira scores more marks than Sujatha the later should leave school. Athira, seeing no other solution but to score better than her mother, starts studying well. She scores a "personal" record 58% marks in her next mathematics exam. Sujatha is happy, and leaves school. Sujatha, being naïve, decides to meet the District Collector (Mamta Mohandas) to plan her daughters academic future. She somehow manages get into collector's residence and tells the Collector about her dream to see Athira as a District Collector. The Collector - much to the surprise of Sujatha - tells her that she herself came from a very low income family and couldn't afford to go to expensive private "coaching classes" for Civil Service Exams. Sujatha soon discovers that her daughter only scored good marks in the last series of exams because she didn't want to attend classes with her mother. Determined to change her daughter Sujatha again starts attending the school. Sujatha now starts taking more and more jobs, works late into the night in small restaurants, and saves more and more money for Athira (and to pay out her family debts). One day Sujatha finds out that Athira has stolen her savings to buy expensive school bags, slippers and dress. Sujatha gets humiliated by the landlady to whom she owes money. Athira suspects that her mother is earning money by prostitution. The relation between the mother and daughter reaches an all time low. While going to work Sujatha meets with a road accident and is severely wounded. In the hospital, Athira gets to know that her mother is not doing any prostitution but she is working day and night in a small restaurant in the city. Athira visits her mother in the hospital and asks for forgiveness and vows to "study hard from now on". Reformed Athira passes 10th class exams (SSLC) with good marks, along with Sujatha, and she eventually fulfils her mother's dream by becoming a District Collector. After being asked what inspired her to apply for the Administrative Service, she answers that she is inspired by her mother, who now tutors economically backward students for free.
